On Sunday in Union Square a man walked by stacks of old computers wrapped for recycling at the annual After the Holidays Electronic Waste Recycling Drive. More than 1,000 New Yorkers dropped off a total of 30 tons of old computers, TVs and cell phones at the event, sponsored by the Lower East Side Ecology Center. L.E.S.E.C. also collected postcards in support of Intro. 104, a City Council bill that would require electronics manufacturers to take back old equipment  which contains toxic metals  for recycling or proper disposal.
